1 、工作原理 </p> <p> 差壓式液位汁是利用容器內(nèi)液位改變時，由液柱產(chǎn)生的靜壓也相應(yīng)變化的原理而工作的，如圖1所示。差壓變送器的一端接液相，另一端接氣相時根據(jù)流體靜力學(xué)原理，我們知道，變送器正壓室受到的壓力為：Pl=P氣十ρgH。式中H：液位高度;ρ：介質(zhì)密度;g：重力加速度;P氣：氣相壓力。圖1差壓變送器測量液位計示意圖差壓變送器負(fù)壓室壓力P2=P氣，則正負(fù)壓室的差壓為：ΔP=P1-P2。通常，被測介質(zhì)的密度是已知的。因此，測得差壓值就能知道液位高度。

1、磁翻板液位計在經(jīng)過較長時間的使用后，由于浮筒會吸附介質(zhì)中的污垢，因此磁翻板液位計每年不定期清洗浮筒內(nèi)雜質(zhì)，每天至少應(yīng)清洗一次。 </p> <p> 2、清洗時，應(yīng)先打開磁翻板液位計鐵管的旋帽，小心拿出磁翻板液位計，再把設(shè)備周圍地鐵屑、臟物等一一清掃干凈。 </p> <p> 3、清洗前，應(yīng)將磁翻板液位計放置整齊，管道、線路條理有序，同時注意做好防護(hù)措施，避免磁翻板液位計內(nèi)有腐蝕性液體流出造成損傷。 </p> <p> 4、磁翻板液位計清洗時，可以使用三氯乙烯或乙醇（俗稱酒精）注入引壓孔至其高度二分之一處，放置浸泡大約5至10分鐘，然后輕微晃動，重復(fù)多次，直到清洗干凈為止。禁止使用任何器具清洗引壓孔，以免損壞敏感芯子感壓膜片，產(chǎn)生誤差。 </p> <p> 5、在清潔磁翻板液位計時，不能用硬度過大的刷子或金屬工具，以避免損壞敏感芯子及接口螺紋，造成局部損壞； </p> <p> <span style="font-size:12px;">6、清洗完畢后將液位計慢慢放回鐵管中，放置到鐵管的低部，將旋帽安裝回原處即可，再將卸下清洗后的液位計重新安裝。為確保采樣數(shù)據(jù)的正確性，必須再次對照水閘同一水位，并對儀表的檢測值進(jìn)行矯正。</span> </p>

alt="湖南雷達(dá)液位計批發(fā)價格,位計" src="https://tyunfile.71360.com/UploadFile/jszhck/637412295617832598/6855851.png"></div><p> 光電式液位開關(guān) </p> <p> 優(yōu)點：沒有機(jī)械運(yùn)動部件,可靠性高；體積小，性價比高；液位控制精度高，可重復(fù)性好。 </p> <p> 缺點：不適用于冷凍液體和結(jié)晶液體。 </p> <p> 超聲波液位開關(guān) </p> <p> 優(yōu)點：超聲波液位計是非接觸測量方式，±0.2%精度，1-25米量程，優(yōu)異的聚焦：5度聲束角，多種傳感器材質(zhì)，內(nèi)置全量程溫度補(bǔ)償。超聲波液位計測量有腐蝕（酸、堿）的介質(zhì)、有污染的場合，或易產(chǎn)生粘附物的物質(zhì)。適合于那些無法用物理方式接觸的液體。 </p> <p> 缺點：1：與被測介質(zhì)粘度有關(guān)，被測介質(zhì)粘度較大時不鞥測量； </p> <p> 2：受溫度影響，當(dāng)溫度高時，傳播速度回發(fā)生變化，儀表反應(yīng)遲緩，會延遲報警。 </p><p> 浮球液位計 </p> <p> 1、工作原理 </p> <p> 浮球液位計結(jié)構(gòu)主要是基于浮力和靜磁場原理設(shè)計生產(chǎn)的。帶有磁體的浮球在被測介質(zhì)中的位置受浮力作用影響，液位的變化導(dǎo)致磁性浮子位置的變化。浮球中的磁體和傳感器（磁簧開關(guān)）作用，使串連入電路的元件（如定值電阻）的數(shù)量發(fā)生變化，進(jìn)而使儀表電路系統(tǒng)的電學(xué)量發(fā)生改變。也就是使磁性浮子位置的變化引起電學(xué)量的變化。通過測量電學(xué)量的變化來反映容器內(nèi)液位的情況。 </p> <p> 2、特點及適用場合 </p> <p> 2.1結(jié)構(gòu)簡單、使用方便 </p> <p> 2.2性能穩(wěn)定、使用壽命長、便于安裝維護(hù) 幾乎可以適用于各種工業(yè)自動化過程控制中的液位測量和控制，可以運(yùn)用于石油加工、食品加工、化工、水處理、制藥、電力、造紙、冶金、船舶和鍋爐等領(lǐng)域中的液位測量、控制與檢測。孔板式超聲波液位計結(jié)構(gòu)牢固,性能穩(wěn)定可靠,使用壽命長;</p><div style="width:100%;text-align: center;"><img

雷達(dá)物位計已成為物位測量儀表市場上的主流產(chǎn)品，主要分為雷達(dá)物位計和導(dǎo)波雷達(dá)物位計。 </p> <p> 雷達(dá)物位計發(fā)射功率很低的極短的微波通過天線系統(tǒng)發(fā)射并接收。雷達(dá)波以光速運(yùn)行。運(yùn)行時間可以通過電子部件被轉(zhuǎn)換成物位信號。一種特殊的時間延伸方法可以確保極短時間內(nèi)穩(wěn)定和精確的測量。即使存在虛假反射的時候，較新的微處理技術(shù)和軟件也可以準(zhǔn)確地分析出物位回波。通過輸入容器尺寸，可以將上空距離值轉(zhuǎn)換成與物位成正比的信號。儀表可以空倉調(diào)試。在固體測量中的應(yīng)用可以使用K-頻段的高頻傳感器。由于信號的聚焦效果非常好，料倉內(nèi)的安裝物或倉壁的粘附物都不會影響測量。雷達(dá)液位計記錄脈沖波經(jīng)歷的時間，電磁波的傳輸速度為常數(shù)，算出液面到雷達(dá)天線的距離，知道液面的液位。浙江導(dǎo)波雷達(dá)液位計找哪家</p><p

超聲波液位開關(guān)內(nèi)部壓電晶體的叉形探頭中間被空氣隔開，一個晶體振動頻率為1.5MHz把聲音信號傳到空氣間隙中間，探頭浸入液體時，晶體，聲波偶合，超聲波液位開關(guān)改變狀態(tài)。 </p> <p> 技術(shù)指標(biāo)：比較大電纜長度：30m工作溫度：標(biāo)準(zhǔn)型:0~80℃中溫型：0~120℃環(huán)境溫度：-40~70℃工作壓力：常壓介質(zhì)密度：≥0.6g/cm觸點容量：220VAC </p> <p> 10A 電氣接口：M20*1.5防護(hù)等級：IP65過程連接：HG20592~20635-97 </p> <p>

優(yōu)點：振動音叉開關(guān)能真正地免受流量、氣泡、湍流、泡沫、振動、固體含量、沾敷、液體特性以及產(chǎn)品變化的影響。并且不需要校準(zhǔn)，只需要經(jīng)歷短的安裝過程便能完成安裝。無活動零件或縫隙真正實現(xiàn)免維護(hù)。強(qiáng)大的自檢查與診斷功能保證了高低物位測量的高可靠性，某些型號的物位計甚至可以在出現(xiàn)故障之前，繪出性能曲線和發(fā)送故障趨勢信號。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 缺點：音叉開關(guān)不適合用于非常粘的介質(zhì)。導(dǎo)致叉子被連接在一起的叉間物料堆積，將干擾物位檢測。 </p> <p> <br /> 湖南雷達(dá)液位計批發(fā)價格</p></p><br /><p>文章來源地址:
